Description

The pulley structure of skateboarding

The utility model relates to a kind of structure technology of skateboarding, is a kind of pulley structure of skateboarding.

Skateboarding is a kind of apparatus that utilizes pulley to produce the displacement action of advancing, the training that the sense of equilibrium can be provided and have the speed pleasant sensation, for general young man and teenager, be quite attractive challenge, so be extremely welcome in recent years sporting goods; But, up to now, existing skateboard on the market, all only be confined to the variation of template style and material aspect, but ignored the improvement that wheel body slides, this is that the fancy slide plate can't have breakthrough and increase variational main cause always, and only can provide the contact of plane formula to support, and has no protection concerning user's safety; And in recent years; in the various motion; be target to pursue extreme sport invariably; so-called extreme sport is that the mankind's locomitivity is brought into play to its limit; such as: slide plate; skating; multiple motion such as racing car; the general mood that the extreme sport studied intensively is all arranged; because extreme sport often has highly difficult action to break through, except that the sporter must have strong challenge desire, suitable and practical appliance applications; then be to assist a ruler in governing a country the maximum power-assisted that the sporter progresses greatly every day; and the main sharp weapon of protection sporter personal safety, therefore, the known Roller of skateboard that has only horizontal coasting ability; its structural design has improved necessity in fact, and just foot is in the demand that meets the slide plate extreme sport.

Main purpose of the present utility model is to improve the skateboarding wheel body structure of commonly using, a kind of pulley structure of new skateboarding is proposed, this structure is on the pulley of putting body winding slide plate with lock is pivoted frame, extend out two dividing plates that split suitable distance, and utilize a dividing plate and an assembly pulley to articulate, make the long wheel body in the assembly pulley just can be embedded in the frame inside that is pivoted, short wheel body then is positioned at the dividing plate outside, borrow long, the imploded arcs of short wheel body and face profile collocation, generation has the effect of sliding of plane and non-planar concurrently, and the use effect of being good at bringing into play the slide plate extreme sport is especially arranged.

An inferior purpose of the present utility model is to improve the skateboarding wheel body structure of commonly using, a kind of pulley structure of new skateboarding is proposed, this structure can be changed two groups short wheel bodys the fan-shaped wheel body of circle footpath greater than long wheel body and the bent arc profile of tool, makes to have to extend and add to greatly enhance the result of use that wheel body contacts bent radian.

A purpose more of the present utility model is to improve the skateboarding wheel body structure of commonly using, and proposes a kind of pulley structure of new skateboarding, and this structure can be assembled on the above skateboarding structure of two-wheeled or two-wheeled and use, and it is unrestricted that assembling is used.

Another purpose of the present utility model is to improve the skateboarding wheel body structure of commonly using, a kind of pulley structure of new skateboarding is proposed, the imploded arcs profile of the long wheel body of this structure, can be in response to the different curvatures of travel path, produce bridging or, having the smooth-going and stable effect that slides that non-single-point supports especially of arc anastomosis against contact.

The technical solution of the utility model and being characterised in that: the pulley structure of this skateboarding, the pulley of putting body winding slide plate with lock is pivoted on the frame, mainly comprise long wheel body, short wheel body and the pulley frame that is pivoted, it is characterized in that: the pulley frame that is pivoted, its end face is provided with a lock and puts body, both ends extend out the dividing plate of suitable branch distance, on dividing plate, set up locating hole in correspondence with each other separately, the axostylus axostyle of one two ends tool thread segment is placed through in the locating hole, be placed in a long wheel body in axostylus axostyle stage casing, its shape profile is the indent arcuation, be embedded at the be pivoted inside of frame of pulley, be nested with two short wheel bodys respectively in axostylus axostyle two end positions, it is the same with long wheel body wheel footpath size that it takes turns the footpath, long, be embedded with bearing respectively in the two ends mesopore groove of short wheel body, and be positioned in the dividing plate, the outside, by nut and the locking of axostylus axostyle thread segment, before two groups of these pulley structures are put body and are assembled in the slide plate bottom respectively by lock, on the back position, group constitutes the pulley structure of the coasting ability with plane and non-planar, it must be contacted in the horizontal and bending arc shape collocation that utilizes pulley, finish the exceedingly difficult movements of slide plate extreme sport, and then reach and improve slide plate and be applicable to various sliding paths and strengthen slide plate and support steadily, the practical purpose of security.This structure is applicable to two-wheeled or the skateboarding structure more than the two-wheeled; The imploded arcs profile of the long wheel body of this structure can be in response to the different curvatures of travel path, produce bridging or against contact, having the smooth-going and stable effect that slides that non-single-point supports especially of arc anastomosis.The wheel body that wherein is positioned at the dividing plate outside is changed into the fan-shaped wheel body of circle footpath greater than long wheel body and the bent arc profile of tool.

Major advantage of the present utility model is that the new-type structure of this kind produces the effect of sliding that has plane and non-planar concurrently, and the use effect of being good at bringing into play the slide plate extreme sport is especially arranged, and makes to have to extend and add to greatly enhance the result of use that wheel body contacts bent radian.It is unrestricted that assembling is used.Can be in response to the different curvatures of travel path, produce bridging or, having the smooth-going and stable effect that slides that non-single-point supports especially of arc anastomosis against contact, reach and strengthen slide plate and support steadily, have more security.
